A timing belt is a small but crucial engine part that can keep a motor running properly and improve fuel efficiency. While not all engines have belts, they are the most common over timing chains or timing gears. The belt wraps around a series of gears at the front of the engine to aid in "timing" the opening and closing of fuel valves. Made from the same material as most other engine belts, they are not the most durable part and will wear out eventually. Timing belts are normally used in smaller engines, but only rarely in larger ones.

The function of a timing belt is to turn the camshafts at exactly one-half the speed of the crankshaft. The camshaft manages the opening and closing of the intake and exhaust valves with the up-and-down movement of the pistons in the cylinders. The valves must open and close at the proper rate, so the timing belt must be calibrated properly to move the valves in time with the correct motion of the pistons. The camshaft and crankshaft gear both have a timing mark on them that must be aligned correctly prior to putting the timing belt on the gear teeth or the engine will not run.

Defective Symptoms

Length of Use

A timing belt will last from 50 000km to 120 000km’s, depending on the make and model of the car, how it's driven and how well the vehicle is maintained. Other factors can contribute to how long the timing belt might last, including manufacturer defects. Check your owner's manual to get an idea of how long timing belts on your particular make and model last.

Preventative Care

If you perform regular maintenance on your vehicle, your mechanic will typically notice timing belt wear when you bring the car in for servicing. If the mechanic suggests you replace the timing belt, it's best to follow his advice. Doing so will save you a lot of trouble and money down the road.

Preventative Care

Some common signs the timing belt could be wearing out include: Your car is spewing out more exhaust than usual. Your high-mileage car is hard to start. The engine vibrates, causing your car to shake. Your car shuts off while driving and spins over quicker than normal when you're trying to restart it.

When the Timing Belt breaks or fails

If the car bucks and stops running, it's probably too late. The belt is probably broken or has otherwise failed. The type of engine you have will determine how much collateral damage occurs when the timing belt breaks. In interference engines, a timing belt break could cause severe valve damage and damage to other engine parts. A noninterference, also known as "free-wheeling," engine typically doesn't suffer as much damage. But it will still cost you quite a bit to replace the timing belt once it's broken and other parts that were damaged when the belt broke.

Tip

While having the timing belt replaced, you should also consider replacing the water pump, belt tensioner, thermostat and camshaft seals. They'll probably already be worn or about to wear out. Replacing them at the same time as your timing belt can save you money on labor and save you extra trips to the mechanic.
